Aching muscle minutes after drinking alcohol

I’m 42 and only drinking very occasionally. I partied a lot in my younger years but from the ages of about 32 it’s become only every 3-4 months that I have any alcohol at all. In the last few years I’ve developed an issue where a few minutes after I’ve had my first sip of any type of alcoholic drink I feel intense muscle aching in my legs, arms and abdomen. The pain kids of moves from one place to another and can last 5-10 minutes. Once I’m past the first couple of drinks it generally doesn’t happen again. Does anyone else experience this or know what could cause it? I have asked a doctor but they were unsure and said it’s possible allergy but I’m not sure about that as it doesn’t happen after a couple of drinks in.

I should add that I’m very healthy apart from this, regular gym goer, healthy eater. All my health stats/tests come back great.
